[0026] It should be noted that, in this embodiment, the first limiting collar 13 is used to connect two adjacent positioning bolt bodies 10 one by one. Compared with a single independent positioning bolt body 10, this method increases stability and makes the mold bag laying more stable.

[0027] After being used for a certain period of time, the positioning bolt bodies 10 may become loose. At this time, the two connecting chains 162 on the connecting chain 16 are stacked together using bolts and nuts 17, and fixed with bolts and nuts 17, so that the two adjacent positioning bolt bodies 10 can be quickly fastened; among them, the gasket 171 increases the stability of the fixing of the bolts and nuts 17.

[0028] like Figure 1 、 2 As shown in , 4 , an auxiliary limiting assembly 15 is provided at the other end of the connecting chain 16; the auxiliary limiting assembly 15 includes a limiting plate 151 connected to the other end of the connecting chain 16, a plurality of prefabricated holes 152 are passed through the top of the limiting plate 151, and a plurality of cement nails 153 are passed through the top of the limiting plate 151 and located in the prefabricated holes 152.

[0029] It should be noted that, in this embodiment, the positioning bolt body 10 is formed by arranging a plurality of positioning bolt bodies 10 linearly in the longitudinal and transverse directions on the bank surface, and cooperating with each other.

[0030] The two second limiting collars 14 are each connected to a connecting chain 16, and the other end of the connecting chain 16 is connected to a limiting plate 151. The limiting plate 151 is provided with a plurality of prefabricated holes 152. When in use, the limiting plate 151 is fixed to the cement ground at the edge of the embankment by cement nails 153.

[0031] The entire auxiliary limiting assembly 15 is used to assist in limiting and fixing a single positioning bolt body 10 , thereby further increasing the stability of the positioning bolt body 10 .

[0032] like Figure 1 、 2 4, including a positioning bolt body 10, the positioning bolt body 10 includes at least two bolts 11, the top of the bolt 11 is provided with a connecting top block 12, one side of the bolt 11 is provided with a side plate 111, and the top of one end of the bolt 11 is penetrated by a rope reserved hole 112; the bottom of the side wall of the first limiting collar 13 is provided with a thread, and the first limiting collar 13 is threadedly connected to the inner wall of the connecting top block 12;

[0033] The first limiting ring 13 and the second limiting ring 14 have the same structure.

[0035] The working principle of this utility model is:

[0036] The two pegs 11 are connected to each other through the connecting top block 12 to form a whole, forming the most basic positioning structure of the positioning bolt. The side plate 111 increases the load-bearing surface of the pegs 11, thereby increasing its stability. By applying impact force to the connecting top block 12, the two pegs 11 are nailed into the inclined surface of the embankment and fixed. This serves as a basis for the subsequent laying of the mold bag to limit the bone screws. The rope reserved hole 112 is used when laying the mold bag.

[0037] The positioning bolt body 10 is formed by arranging a plurality of positioning bolt bodies 10 linearly in the longitudinal and transverse directions on the bank surface and cooperating with each other;

The limiting plate 151 is provided with a plurality of prefabricated holes 152. When in use, the limiting plate 151 is fixed to the cement ground at the edge of the embankment by cement nails 153.

[0039] The entire auxiliary limiting assembly 15 is used to auxiliary limit and fix a single positioning bolt body 10, further increasing the stability of the positioning bolt body 10;

[0040] The first limiting collar 13 is used to connect two adjacent positioning bolt bodies 10 one by one. Compared with a single independent positioning bolt body 10, this method increases stability and makes the mold bag laying more stable.

[0041] After being used for a certain period of time, the positioning bolt bodies 10 may become loose. At this time, the two connecting chains 162 on the connecting chain 16 are stacked together using bolts and nuts 17, and fixed with bolts and nuts 17, so that the two adjacent positioning bolt bodies 10 can be quickly fastened; among them, the gasket 171 increases the stability of the fixing of the bolts and nuts 17.

[0042] The above embodiments are only for illustrating the technical idea of ​​the present invention and cannot be used to limit the protection scope of the present invention. Any changes made on the basis of the technical solution in accordance with the technical idea proposed by the present invention shall fall within the protection scope of the present invention.
